EURUSD V2.0 策略

针对 EURUSD 的均值回归策略,利用长期简单移动平均线 (SMA) 和基于 ATR 的波动性过滤。

策略逻辑

  • 根据所选周期计算长度为 MA Length 的 SMA。
  • 当价格在 SMA 之上并回落到 Buffer 点以内,同时 ATR 低于 ATR Threshold 时开
  • 当价格在 SMA 之下并接近到 Buffer 点以内,同时 ATR 较低时开
  • 仓位大小由账户余额和 Risk Factor Z 共同决定。
  • 止损与止盈按固定点数距离设置。
  • 平仓后,价格需距离入场价 Noise Filter 点后方可再次交易。

参数

  • MA Length – SMA 周期(默认 218)。
  • Buffer (pips) – 触发入场的最大 SMA 偏离(默认 0)。
  • Stop Loss (pips) – 止损距离(默认 20)。
  • Take Profit (pips) – 止盈距离(默认 350)。
  • Noise Filter (pips) – 重新允许交易的价格距离(默认 50)。
  • ATR Length – ATR 计算周期(默认 200)。
  • ATR Threshold (pips) – 允许入场的最大 ATR(默认 40)。
  • Max Spread (pips) – 允许的最大点差(默认 4)。
  • Risk Factor Z – 资金管理系数(默认 2)。
  • Candle Type – 使用的 K 线周期(默认 15 分钟)。

该策略使用市价单进行进场和出场。
